1. What is Total Daily Energy Expenditure?

Total Daily Energy Expenditure (TDEE) represents the total number of calories your body burns in a day, including basal metabolic rate (BMR) and physical activity. It's crucial for weight management and nutritional planning.

2. How Does the Calculator Work?

The calculator uses the TDEE formula:

Where:

• \( BMR \) — Basal Metabolic Rate (calories burned at rest)
• \( Activity\ Multiplier \) — Factor based on physical activity level

Activity Multipliers:

• Sedentary (little to no exercise): 1.2
• Lightly Active (light exercise 1-3 days/week): 1.375
• Moderately Active (moderate exercise 3-5 days/week): 1.55
• Very Active (hard exercise 6-7 days/week): 1.725
• Extremely Active (very hard exercise, physical job): 1.9

3. Importance of TDEE Calculation

Details: Knowing your TDEE is essential for weight management. To lose weight, consume fewer calories than your TDEE; to gain weight, consume more. It helps create personalized diet and exercise plans.

4. Using the Calculator

Tips: Enter your BMR in kcal and select your activity level based on your weekly exercise routine. Ensure BMR is calculated accurately for best results.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between BMR and TDEE?
A: BMR is calories burned at complete rest, while TDEE includes all daily activities and exercise.

Q2: How accurate are activity multipliers?
A: They provide estimates. Individual variations in metabolism and activity intensity can affect accuracy.

Q3: Should I use TDEE for weight loss?
A: Yes, consuming 500 calories less than your TDEE typically results in about 1 pound of weight loss per week.

Q4: How often should I recalculate my TDEE?
A: Recalculate every 4-6 weeks or after significant weight changes or activity level modifications.

Q5: Can TDEE change throughout life?
A: Yes, TDEE decreases with age due to reduced muscle mass and metabolic rate, and increases with muscle gain.
